Grand Tower: Germany’s Tallest Residential High-Rise in Frankfurt am Main

Frankfurt am Main continues to build upwards. At the gateway to the Europa district, between the main railway station and the fairgrounds, four new, top-class skyscrapers have been erected concurrently. These include the Grand Tower, which was completed last year on Frankfurt’s Europa-Allee. At just under 180 m in height, the tower designed by architect Magnus Kaminiarz († 2019) and developed by GSP Städtebau is currently the tallest residential high-rise in Germany. It has 44,000 m2 of total floor area, of which around 32,000 m2 are devoted to living space. Honeycomb-like loggia elements surround the slender tower and structure the curvy glass-aluminum façade, which measures about 20,000 m2. Nearly every apartment has its own balcony that offers residents a great degree of private space; many also offer exclusive views over the city.

A Sophisticated Access System
Forty-seven residential levels accommodating 413 living units, apartments and stylish penthouses rise above the ground floor, which is home to the lobby and separate retail spaces. The modular structure of the tower allows diverse floor plans ranging from 41 to 300 m2, open spatial designs and various angles of view over the city. More than half the apartments have three or four rooms; nearly one-third are smaller living spaces. In order to avoid flats that face north only, the planners arranged the apartments over a rhombic area facing north and south. The ground-floor lobby is 6 metres tall and is home to the concierge service; the private, 150-m2 sunset deck is located 141 m up on the 43rd floor and the 1,000-m2 Grand Terrace is on the 7th floor: all were designed by studio architects. Three technical levels top off the tower. The building is accessed via five elevators − including one for firefighters − by using a sophisticated access-control and user information system for residents and their guests.

Exterior Sunshade
The planners entered new territory when it came to summertime heat protection, which must be ensured despite, or perhaps even because of, the extensive glazing and structural specifications such as wind stability of 24 m/s. Until now, virtually no residential building of this height has had an exterior sunshade. In close collaboration among the architects, the façade engineers and the sunshade specialists, bespoke project-specific solutions were developed and completely integrated into the façade. To a certain extent, residents can use the shade individually as needed. The steering system, which is based on a wind appraisal, accounts for the position of the sun, wind direction, storey height and building geometry.
